Before you book: air-to-air heat pumps in Portstewart
A heat pump suits most Portstewart homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Extensions and garden rooms in Portstewart that are hard to connect to the main heating can have their own air-to-air unit. A survey in Portstewart covers indoor unit positions, pipe routes and hot water for homes across County Londonderry.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
- Flats and apartments with storage or panel heaters
What's included
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
Flats in Portstewart on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Portstewart home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey checks the unit position against them.

Air-to-air heat pumps in Portstewart: questions
How long does a heat pump survey take in Portstewart?
A home survey in Portstewart usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How long does installation take in Portstewart?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Portstewart home states the expected time.
Can you service a heat pump in Portstewart that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Portstewart, whoever fitted them. Tell us the make and model when you book.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
